, DUPLEX PENHOLDER.

SPECIFICATION forming part of Letters Patent No. 654,989, dated. July31, 1900.

Application filed April 9, 1900.

To ctZZ whom it may concern:

Beit known that We,HARVEY LONG-ENECKER and FRANK LONGENEOKER, citizensof the United States,and residents of Beamsville, in the county of Darkeand State of Ohio, have invented a new and Improved Duplex Penholder, ofwhich the following is a full, clear, and exact description.

The invention relates to penholders in which the case contains twomovable pen-sockets so arranged that when one is projected the other isretracted.

The object of the invention is to provide a new and improved duplexpenholder having a simple mechanism which permits a ready projection ofone pen-socket and at the same time causes a retraction of the otherpensocket to enable the penman to make use of separate pens fordifferent inks and without one pen interfering with the other.

The invention consists of novel features and parts and combinations ofthe same, as

Will be fully described hereinafter and then pointed out in the claims;

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a plan view of the improvement. Fig. 2 is a longitudinalsectional elevation of the same. Fig. 3is a similarviewof the same withone pen-socket projected and the other retracted. Fig. 4 is aperspective view of one pen'socket, and Fig. 5 is a like view of theother pen-socket.

The case or body A of the duplex penholder is made hollow and is closedby a cap A,'and in said case are mounted to slide longitudinally twopen-sockets B 0, arranged to carry pens D D of theusual construction. Astopscrew E engages the uppermost pen-socketB and extends through anelongated slot A in the casing A, so as to allow the operator to movethe pen-socket B longitudinally and at the same time limit thelongitudinal sliding movement thereof. The rear ends of the pensockets Band C are formed with nuts 13 C, respectively, of which the nut Bengages the right hand thread F of a screw-rod F,mounted to turn at itsrear end in a suitable socket G, carried by the fixed cap A. The Othernut Serial No. 12,094. (No model) (11 engages the left=hand thread F ofthe screwrod F, so that when the operator imparts a forward movement tothe stop-screw E, and consequently to the pen-socket B, then the nut Bturns the screw-rod F, and the latter thereby causes the nut O to travelrearward on the threads F whereby the pen socket Cl is retracted. WVhenthe operator moves the stop-screw E rearwardly, then the pen-socket B isretracted, and in doing so causes a turning of the screw-rod F in areverse direction to cause the nut O to travel forward on the threads Fwhereby the pen-socket O is projected. Thus it will be seen that whenmovement is given to one pen-socket in one direction the otherpen-socket is moved in an opposite direction. By the arrangementdescribed the two' pen-sockets B and O are mounted to slide one upon theother and preferably for this purpose are made semicircular incross-section, as indicated in Figs. 4: and 5. By this arrangement theoperator can project either of the pens D or D without one peninterfering with the other to allow the use of difierent inks on thepens or to use the pens for other purposes.

Having thus fully described our invention, we claim as new and desire tosecure by Let ters Patentl. A penholder, comprising a case, a right andleft hand screw-rod mounted in said case, and pen-sockets engaging theright and left hand threads of the screw-rod respectively, whereby whenone socket is moved in one di rection the other is caused to travel inan opposite direction, substantially as shown and described.

2. A penholder, comprising a case, a right and left hand screw-rodmounted to turn in said case, and pen-sockets mounted to slide in thecase and engaging the right-hand and left-hand threads of the screw-rodrespecti vely, whereby when one pen -socket is moved in one directionthe screw-rod is turned and the other pen-socket is caused to travel inan opposite direction,substantially as shown and described. V

3. A penholder, comprising a case, a right and left hand screw-rodmounted to turn in said case, pen-sockets mounted to slide longitudinally in said case, and a nut in each socket, one nut engaging therighthand thread of the screw-rod and the other nut en= gaging theleft-hand thread of said screw-rod,

substantially as shown anddescribed. V

4. A penholder, comprising a case, a right and left hand screw-rodmounted to'turn in said case, pen-sockets mounted to slide10ngitudi'nally in said case, a nut in each socket, 7

one nut engaging the right-hand thread of the screw-rod and the othernut engagingthe left-hand thread of said screw-rod,and means, as setforth, and connected with one of the Y pen-soekets to allow of movingthe same in either direction.'

7 In testimony whereof we havesigned our names to this specification inthe presence of I 5 two'subscribing witnesses.
